The creators of Flow and Flower are busy developing Journey. It is an online adventure game for the Playstation Network, developed by thatgamecompany
The main character is lost in the desert with no idea about time and place or even themselves. During the whole course of the game, the main character travels towards a mountain (which is the only point of interest in the desert) in hopes of finding about the Civilization that inhabited the desert in the forgotten past.
The game will have very simple controls and realistic sand and wind movements. It lacks any enemies, instead there are a number of obstacles of varying difficulties that the player must get through. Since this is an "online" game, players will also come across other people who are travelling through the desert with a similar goal.
